US judge bars OpenAI from using 'Cameo' in Sora app

A US federal judge has temporarily barred OpenAI from using the word “cameo” for features in its Sora app following a trademark dispute.

The order, issued by District Judge Eumi K. Lee on November 24, stops OpenAI from using “cameo” or similar terms like “Kameo” and “CameoVideo” for Sora, an AI-powered video app, until December 22.

The decision follows a lawsuit filed in October by Cameo, a US-based platform that sells personalized celebrity video messages, after OpenAI launched a Sora feature called “Cameo.”

Cameo alleges OpenAI’s use of the word could confuse consumers.

OpenAI has disputed the claim, saying it does not believe anyone can exclusively own the term.

A hearing to decide if the ban should become permanent is set for December 19.

🧠 Food for thought

Implications, context, and why it matters.

Cameo trademarks at issue in the injunction

Baron App, Inc. d/b/a Cameo owns a registered trademark for CAMEO CALLS 1 2. It was filed in March 2021 and registered in January 2022. The registration covers software and electrical products under Class 009 (a Nice classification for software and electronic devices) 1 2.
The available records do not verify the status of standalone CAMEO filings by Baron App, Inc. 3.
This puts Cameo’s trademark strength at issue for any injunction beyond the current temporary order. OpenAI is contesting Cameo’s claims in the case 42.
A December 19 hearing will decide whether to extend the ban or make it permanent. The outcome will hinge on proof of consumer confusion, meaning whether ordinary buyers are likely to mistake the source of the services, plus the commercial strength of the marks in video services beyond celebrity messaging 4.
